Can humans exist without some people ruling and others being ruled? The founders of political science did not think so. "I put for a general inclination of mankind, a perpetual and restless desire for power after power, that ceaseth only in death," declared Thomas Hobbes. Because of this innate lust for power, Hobbes thought that life before (or after) the state was a "war of every man against every man"—"solitary, poor, nasty, brutish and short." Was Hobbes right? Do humans have an unquenchable desire for power that, in the absence of a strong ruler, inevitably leads to a war of all against all? To judge from surviving examples of bands and villages, for the greater part of prehistory our kind got along quite well without so much as a paramount chief, let alone the all-powerful English leviathan King and Mortal God, whom Hobbes believed was needed for maintaining law and order among his fractious countrymen.
